"My job as a parent is to celebrate them and to love them and to make sure that they have everything they need in order to be what they want to be, and I will do everything in my power for my kids to have that right and to be protected within that."

She credits her mother for teaching her how to be a tolerant and accepting person.

"You know, I grew up in (South Africa) where people lived with half-truths and lies and whispers and nobody said anything outright, and I was raised very specifically not to be like that," Theron said.

"I was taught by my mom that you have to speak up. You have to be able to know that, when this life is over, you'll have lived the truth you're comfortable with, and that nothing negative can come from that."

Theron, who founded her own organisation CTAOP that campaigns for HIV awareness, has been an LGBTQ activist for many years.

In 2009, she announced on The View that she wouldn't get married to her then-boyfriend Stuart Townsend until everyone in the United States had a right to marry.

"I have so many friends who are gays and lesbians who would so badly want to get married, that I wouldn't be able to sleep with myself," she said while on the show.
